mrsovsusnrm The METHOD or PR BLLING SLEDS BY HAND,

TO ALL WHOM IT MAY CONCERN:

Be it known that we, J. A. BARTLETT and FRANK WALMAN, of Orfordville, inthe county of Rock, and State of Wisconsin, have inventeda new anduseful Improvement in Hand-Sleds; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing bad to the annexed draw ings, making a part of this specification,in which one side of a. hand-sled'is shown in elevation. The parts hereshown in constructing sleds are duplicated.

My ihvention consists in attaching to a hand-sled a system of levers, bywhich such sled may be propelled by hand by the person on the sled; andits use is intended to enable such person to start the sled or move ituntil such time as it may reach a point on any declivity that it willdescend by gravity. The levers may also be used on one side or theother, as may be required, for the purpose of steering the sled whenrunning down bill, by holding back that side until the direction of thesled is changed.

The black lines in the drawings represent the position of the leverswhen not in use; the" red lines show their position when in action. A

A represents the side of any ordinary hand-sled, to which a lever of thesecond order, B, is pivoted at its lower extremity, so as to permit itto be oscillated vertically. The spiral spring C draws down the lever B,to which and to the'sled it is attached, and-retains it when not in use.The slotted arm D is attached by a pivot, on which it turns, to thelever B. The slot encloses a wrist, E, the head of which will not passthrough the slot. This slot is curved, as represented, and the point ofthe arm D turned down, also, as shown.

By the action of these levers, of which one is placed on each side, thesled may be forced forward on the snow or ice, or steered in runningdown hill, as already stated. A

Having fully set forth the construction and nature of our improvements,what we claim as our improvement, and desire to secure by LettersPatent, is-

A hand-sled, when constructed with a. system of levers attached thereto,to be operated by hand, for propelling and steering the samesubstantially as set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses,

J. A. BARTLETT,

FRANK WALMAN Witnesses ISAAC Rocnns, THOMAS S. Fnosr.
